### Chain asynchronous functions
|
|
|
|
Loop through an array of functions containing asynchronous events, calling `next` when each asynchronous event has completed.
|
|
|
|
```js
|
|
const chainAsync = fns => { let curr = 0; const next = () => fns[curr++](next); next(); };
|
|
/*
|
|
chainAsync([
|
|
next => { console.log('0 seconds'); setTimeout(next, 1000); },
|
|
next => { console.log('1 second'); setTimeout(next, 1000); },
|
|
next => { console.log('2 seconds'); }
|
|
])
|
|
*/
|
|
```
